I know the shutoff solenoid is bad, I took it off and I cant tell what part it moves??? There are also 2 adj. screws on the pump one horizontal an one vertical. the horizontal one in the front seems to push back on the piece that the solenoid pushes forward but I dont know how far back it should come, I dont seem to be gettin alot of fuel out of the inj. lines, but there is plenty coming thru the bypass. does this make any sense to any one out there???
